    Default chevy AC problem

    Help. I cant figure this AC issue out. 2010 chevy Silverado. When I start the truck the AC works just fine. After 10 minutes the air stops blowing out the vents but I can still here the fan running. If I turn off the AC but leave the fan running inside 5 minutes air is flowing and cool. Then I can hit the AC button and it works properly for another 10 min before I have to start the whole process over again. Any thoughts?

    Ive had an issue in my '96 where there is some vent door that can get trapped. Like you, if I have it on max the door gets closed, barely pushes out air but I can hear it blowing loud. When I put it one notch above max it blows cold and strong like it should. Sometimes it will close on its own randomly. I have no clue how to fix it.

    I've had the exact same issue with 13 Tahoe. Multiple fans replaced etc and no one can figure out WTF is going on.
